Question

Suppose you measure the dameter af a balloon contal ning methane gas (CH) and an unknown gas aver a period of twa hours and the following data is collected. Table 1: Time and Volume Data Time (min) Volume of Methane Gas (mL) Volume of Uniknown Gas 1 Unknown Gas 2 (mL) Volume of (mL) 47.7 40.D 31.0 15 45.3 38.4 30.0 36.9 35.3 30. 42.9 29.1 45 40.6 28.1 60. 37.7 33.8 27.1 75 35,2 32.2 26.2 32.4 90. 30.7 25.2 105 29.7 29.1 24.2 27.3 27.5 23.3 120. Graph the data provided above to determine the rate of effusion for the two unknown gases. (Enter your answer to two signticant fiqures) mL/min cas 2 mL/min Determine the identities of the unknawn gases using the following table of molecular weights.
